1, frighten: The courage of koi is relatively small, a little movement will cause them to be frightened, suddenly turn on the light is very easy to frighten them. Moreover, the light in the fish tank is different from the indoor light, which has weakened a lot after passing through the fish tank and water. The lamp in the fish tank is close to the koi, so the reaction is more intense.
2. Light-resistant reaction: Koi also rest, but they don't have eyelids, so we can't judge whether they rest or not from their appearance. Moreover, their sleep is very shallow, and they will wake up with a little sound. If they suddenly turn on the light when they are resting, they will swim around to avoid the light.
of koi running around as soon as the light is turned on? 1. Rest: If you are frightened by the sudden light, you can turn off the light and let them recover slowly. Next time, you can turn on the indoor lights before turning on the lights in the fish tank, so that the koi can get used to it first. Then turn on the light in the fish tank, and they won't be frightened.
2. Turn off the lights immediately: The reaction of avoiding light is not only found in Koi, but also in humans. This is a subconscious reaction that is unavoidable. If you find this is the case, you can immediately turn off the lights in the fish tank and let the koi continue to rest.
